To 1/,ZZ whom, it may concern:

Be itknown that 1,' OTTMAR MEEGENTHA- LER, acitizen of' theUnitedStates, residing at Baltimorein the State of Maryland, have inventedcertain new and useful Improvementsin Linotype-Machines, of which thefoldividual characters are through the instrumentalityl of escapementYmechanism controlled by finger-keys delivered from a magazine, composedor, assembled in line, justified, and presented to the face of themold,l which is then filled with molten type-metal to produce therequired bar or linotype, having on its-face an impression of theassembled matrices." After these operations the matrices are returnedthrough a distributing mechanismtothe magazine from which they started.

The present machine is of the same general character as thoserepresented in numerous Letters Patent heretofore granted to mesuch, forexample, as Lette-rs Patent No.l 317,828, dated May 12, 1885, and No.378,798, dated February 28, 1888,:but more particu-J larly to that formof machine represented-in the Letters Patent granted to me, Nos. 436,531and 436,532, dated September 16, 1890.

The present invention is designed to simplify and to reduce the cost ofmanufacture of the machine; and to this end it consists in variousimprovements' in construction and oper'atiom'which are hereinafter to bedescribed in the specification and finally pointed out in the claims.

Referring now to the drawings, Figure 1 is a front view of my limprovedlinotype-machine, showing such parts 'of the machine as are at the frontthereof.

My improved machine is intended to han- Fig. 25 is.

dle matrices such as are shown in Fig. 33 in connection with the spacebars or wedges such as are shown in Fig. 32. The matrices Y, properlyassorted, are contained in the elevated magazine B, having a series ofchannels through which the matrices descend to the eseapement devices atthe bottom thereof which are actuated through the escapementrods E,operated in turn by the finger-keys D. Similarly the space-bands Z arecontained in the space-band box K and are released therefrom by anescapement device hereinafter to be described, operated from a suitableiingerkey. The discharged matrices, which are released in the desiredorder and one at a time, descend through the guidingchannels G, formedin the assembling-plate, and are re ceived on the upper surface of thetraveling belt H, by which they are delivered successively into andassembled in line in the slotted assembling-box I. The space-bars Z arereleased one at a time when desired in such manner that they descendinto the assembling-box to be added to the line of matrices. As the lineof matrices and space-bars is assembled it is held in compact form bythe yielding resistant J, which is moved to the left step by step as thematrices and space-bars are delivered into the assembling-box by meansof the rotating assembling star or cam H13. When the line is completed,the operator shifts the line manually to the left through the guide Muntil it is introduced and contained within the elevator N. The elevatorN is then man ually released by the operator and descends by its ownweight until the line of matrices and space-bars is brought into properposition in front of the mold. This descent of the elevator throughmechanism hereinafter to be described automatically starts the furtheroperation ofthe machine which effectsthe proper movements of the pot Sand mold O and the justification of the line through thejustifyingpieceQ,the proper locking and clamping of the line longitudinally through thesliding jaw R, and the ejection by means of the pump-plunger S8 of themolten metal from the pot Sinto the mold and against the faces of t-hematrices in front thereof. The parts are then released from theircasting positions and the mold turned through an angle of two hundredand seventy degrees in such manner that the base of the slug is trimmedby reason of its passage against'and by a stationary knife S21. When themold comes to rest again,the ejector starts forward through the mold andforces the linotype out of the mold a distance of about an eighth of aninch, when the knife S22 starts to descend and trims one of the frontedges of the slug or linotype throughout its entire length. After thistrimming of one edge of the linotype or slugthe ejector acts further toforce the linotypc or slug completely from the mold and into theknife-box Si, which contains the knife for trimming the otheredge of theslug or linotypc. In this position the slug is engaged and forcedlongitudinally by IOO IIO

means of a slugshifter SL32 through the knifebox and passes the knifecontained therein,

which trims the other front edge of the linotype or slug throughout itsentire length. The linotype or slug is then'dropped into position to beengaged by a vibrating finger S49, which assembles it with thelLinotypes previously cast in a chase or form S48A in suitable order tobe printed from. During this operation of the ejection' and trimming ofthe slug the elevator N has ascended to the upper portion of themachine, carrying withit the line of matrices-and space-bars until theyregister exactly with the distributing-box'. The line-shifter W thenmoves in to the right, carrying the line of matrices and space-bars intothe distributing-box, where the spacebars are separated from thematrices by means hereinafter to be described and returned to thespace-band box or magazine. The shifter WV continues to move the line ofmatrices toward the distributing mechanism X, where they are engaged oneby `one and returned to their therewith has been stopped automaticallybyY means hereinafter to be described. It will be seen that, as in myprevious patents referred to, the matrices and space-bands are returnedto their proper magazines by a path different from that which theypursued during the course of assemblage, or, in other words, that Istill employ herein what is termed in the art as the circulating system.This feature enables the operator to start in upon the composition of asecondline immediately after he has transferred the first line to theelevator and releases the elevator, so that it may descend to itsoperative position, as the further operations of justifying, casting,ejecting, trimming, and distributing are entirely automatic. l t

Matrices-The matrices employed in the machine are preferably identicalin construc-A tion with those described in my Letters Patent Nos.436,531and 436,532, previously referred to. As shown in Fig. 33, eachmatrix Y consists of a flat rectangular plate of brass,

steel, or likematerial provided in one edge with the intaglio letter ormatrix proper and recessed in its two vertical edges to produce the fourshoulders AY. The matrixis also notched centrally in its upper edge andprovided with sustaining-teeth Y2, the number and arrangement of whichdifferA on matrices bearing different characters, so that they may beemployed as a means of distinguishing betweenand distributing thematrices in the manner set out at length in Letters Patent No. 347,629,granted to me onlthe 17th daypf August, 1886, as well as in numerousother Letters Patent granted to me.

Space-bars.-The space-bars or justifying devices are of the samecharacter as those described in numerous Letters Patent hereferred to.

tofore granted to me-such, for example, as

the Letters Patent previously. referred to, Nos. 436,531 and 436,532.'As shown in Fig. 32, each bar consists of a long wedge Z, carrying onone side a second and shorter wedge Z, which is provided at the upperend with ever, and preferably employ herein its construction with aVertical post or pillar A', on which the keyboard mechanism, theYassembling mechanism, the matrix-magazine, and the distributingmechanism may be firmly placed and secured. This is or may beeffected bythe employment of collars A2 A2, which may be slipped over thepost orcolumn A and secured thereto in the desired position by means ofset-screws A3 A3. This form of construction and arrangement affords me asimple and perfectly practicable method of adjustment and attachment,insuring the independent and exact adjustment of the parts in theirdesired positions.

Thematrt`x-magaztne.-In the present form of machine the matrixreceptacle or magazine B is employed in vertical position instead of ininclined position, as in the Letters Patent Nos. 436,531 and 436,532,previously re- This magazine B consists, essentially, of a front plateB2 and a rearplate B', one overlying the other and divided betweentheirapprox'imate faces into a large number of longitudinal grooves or'receptacles for the matrices by means of the intermediate partitionsBS. (See Fig. 29.) It will be observed that under this arrangement thematrices are held end to end .in rows or lines in their respectivecompartments and permitted to slide freely downward between the plates,those in one line being kept out of contact with the y'adjacent lines.

The construction of the magazine-channels may be similar to thatillustrated and shown in my Letters Patent No. 436,532, it being notedthat the magazine as a whole is flared or made in fan shape, the upperends of the magazine-channels being separated, so as to facilitate theproper distribution of the matrices. From the upper part of the magazineto the lower part the channels gradually converge, so. that at the lowerextremities the series of channels lie closely together and in IOO IIO

close proximity to the receiving-channels G;

This convergence of the channels may be secured by tapering theintermedi-ate partitionplates B8 or in any other suitable manner.

At the lower part of themagazine the front plate B2 is provided withdoors or inlets B3,

hinged upon the transverse rod B5 and ordif narilyretained in closedposition by means of the pivoted springs B1. (See Fig. 2.) By turningthe several springs B4 about their pivots the doors orinlets B3 may beopened, so as to permit access to the magazine-channels. It will benoticed that the location of the doors B3 at the bottom of the plate B2gives a ready and convenient access to the magazine-channels at thefront of the machine and in close proximity to the operator. The rearplate B is provided with lugs B7, Fig. 29, which are adapted to passover and engage the horizontal rod B0, attached to the main frame of themachine and which sustains the magazine in pendent position, so that itmay abut at its lower end against a suitable portion of the frame of themachine and remain in proper adjustment with the assembling-platehereinafter to be described. It will be seen that all that is necessaryto secure a change of fontis to lift the magazine from its position bydisengaging the lugs B7 from the rod B6 and to substitute thereforanother and similar magazine containing the desired characters.

The upper portion or mouth of the magazine which receives the matricesfrom the distributing mechanism is constructed in the following manner:Pivoted at B4G to the plate B2 of the magazine are the two uprightplates B10 B10, slotted vertically, as clearly shown in Figs. 29, 30,and 3l, to receive the reduced ends of the partition-plates B0. Theseends of the partition-plates B0 pass through the vertical slots in theupright plates B10 B10 and are secured therein by means of a rod B11,which passes between the two uprights B10 B10 and through correspondingholes formed in the reduced ends of the partition-plates- This method ofadjustment is one of great simplicity and permits of the ready change ofa partition-plate simply by the withdrawal of the rod B11. Thesepartition-plates B0 are held against vertical displacement by thelongitudinal bearing-bar B11 under which they lie. The portion B12 ofthe partition-plate which is in direct proximity with the mouth of themagazine proper is made corrugated in form, as clearly shown in Figs.29, 30, and 3l. This corrugation is made use of to adjust the passagesto the exact width of the matrix, so as to prevent their turning, as theupper ends of the channels of the magazine B, as before stated, are mademuch wider than is necessary to hold and retain the matrix. The otherend of the partition-plate B0 rests on and within the lerfs ot' aserrated longitudinal plate B13, which is also attached to the upperplate of the magazine. These kerfs or serrations in the plate B13 permita certain amount of resilient lateral movement to the partition-platesB0, which is availed of to stop the distributing mechanism when a matrixis misplaced in the manner hereinafter to be described. It will be seenthat the pivoting of the magazine-mouths at B40 to the magazine properpermits them to be swung out and gives a ready access thereto.

The magazine as a whole is light and simple in construction anddispenses with the heavy and cumbrons metal castings sometimes employedin machines of this class.

Matrix 'delivering mccham'sm.-At the lower end of the magazine I provideeach channel with an escapement which allows the discharge of a singlematrix at a time. This escapement (which is clearly shown in Fig. 5) ispractically identical with that shown and described in my Letters PatentNos. 436,531 and 436,532, previously referred to. It consists of acentrally-pivoted lever or plate E2, pivoted to the magazine andprovided at its opposite ends with the horizontal pins E4 E1, which playalternately into the magazine, so that when the lower pin E4 isretracted to release the lowermost matrix in the line the upper pin E'1will advance into the channel to arrest the downward movement of thenext matrix. A spring E3 acts constantly on the rear end of theescapementlever E2 and assists the inward movement of the upper pin E4when the latter is permitted to act through the operation of themechanism now to be described. The rear portion of the escapelnent leveror plate E2 is formed with a notch, which engages a similar notch in theupper end of the escapement-rod E. These escapement-rods E are locatedat the rear of the assembling-plate and are suitably guided at theirupper portions in a rack or recessed plate C2, attached to theassemblerplate, hereinafter to be described. At their lower ends thesebars E pass into a rack or guide D3, attached to the keyboard, and resttherein upon the bars or plates D2, which in turn are actuated by thefinger-keys D, pivoted at D. Springs E/ E are attached to the guide orrack D3 and to the escapement-rods E in such manner as to hold theescapementrods in a depressed position and are of such strength as toovercome the tendency of the springs E3 to turn the escapement plates orlevers E2 and to withdraw the lower pins E1 from the magazine-channels.Vhen, however, the finger-key D is operated, the escapement-rod E israised against the pressure of the springs E', and the spring E3 is thuspermitted to operate the escapement-lever E2 and withdraw the lower pinE1 in such manner as to permit the release of a single matrix in themanner well known and understood in the art. When the finger-key D isreleased, the spring E restores the escapement-rod E to its originalposition and overcomes the pressure of the spring E3, therebyWithdrawing the upper pin E1 and reinserting the lower pin E4in themagazine-channel, when the next matrix is in position to be released inthe same manner. It will be understood that the escapement-rod E may bedirectly connected to the finger-key D and the plate D2 dispensed with,if desired.

It will be observed that in the present machine I dispense entirely withthe automatic delivery and escapement devices, as illusmachine are ofthe same general character as those described and yclaimed in my LettersPatent Nos. 436,531 and 436,532, previously referred to, but diertherefrom in various minor features and will be hereinafter point-,-

ed out. On being discharged from the magazine the matrices descendvertically to the vertical channels or guides formed within theentrance-plate. These channels or guides G are formed between the platesG4 G4 by partition -plates G3, which are attached to the rear plate G4in the manner clearly shown in Figs.` 5 and 8. Each partition-plate ,G3is provided with two or more projecting lugs, which pass throughcorresponding recesses in the rear plate G4 and are there retained bymeans of the rods G5, which pass through holes in the lugs of thepartition-plates G2, firmly retaining them in position. This form ofconstruction affords a simple and easy means of substituting or changingthe partition-plates G2. The front plate G4 at its lower edge is hingedat Gwinthe manner clearly indicated in Figsl and 2,so as to permitaccess to the guides or channels G. The lower ends of the ribs orpartitions Gsare deflected slightly to the left, as in the formerpatents referred to, and terminate near the inclined belt H, in orderthat the matrices may be presented flatwise and with proper end foremostupon the belt. The upper ends of the escapement-rods E, as beforestated, are contained within and guided by the rack or guide G2. Thisrack G2is attached to the piece or bar G', which is connected to theback plate G1, Figs. 2 and 5. Attached to the bar G' is the springG1,which is also connected to the frame of the machine, Fig. 14. Thepiece G' is provided with elongated screw-holes, through which thesupporting-screws G6 pass into the frame of the machine, Fig. 2. It willbe seen that the tendency of the spring G7 will be to force theentrance-plates and channels G constantly to the left, sliding them uponthe screws G6 until the piece G abuts against the adjustingscrew G8.(See Fig. 2.) In this manner I am enabled to secure an exact andconstant registration between the assembling-channels `and the mouths ofthe magazine and also through the attached rackor guide G2 of theescapement-rods E and the escapement-levers E2.

The belt H is carried around the pulleys H', H7, and H8. Instead'ofemploying the bevel and other gearing of my prior patents motion isdirectly imparted to the upper pulley H' from the pulley H6 on .theintermediate power-shaft H25 through the medium of belt H5 and pulleyH4, which is fast on the rear end of shaft H3. (See Figs. 2, 14, and

assembling.

25.) The pulley H is attached to and turns with the shaft H3 by means ofthe handclutch H2, which is within easy reach of the operator andwhereby he is enabled to stop or start the belt H at will, Figs. 2 and25. It will be noticed that at the lower end of the belt H. instead ofone pulley I employ two pulleys H7 and H11. These two pulleys are solocated as to give the belt an angular turn at its lower end and toinsure the delivery of the matrix in an approximately vertical position,thereby enabling me to dispense with the plate, which is shown asstraddling the lower end of the belt in my Letters Patent No.` 436,532.v

At the lower end-of the assembling-belt H and directly in front of theassembling-box is the assembling star or cam H12, which serves to forcethe descending matrices forward one after another into theassembling-block,wher e they stand in vertical position side by side, asshown in Fig. 2. A guide-piece H14, above the assembling-star H13 andnear the lower end of the assembling-belt H, serves the double purposeof checking the space-bands in their fall and of preventing the matricesfrom falling off the belt H and insures their proper delivery in frontof the assembling-star H13. Motion is imparted to the assembling-starH13 from the belt-pulley Hs in the manner shown in Figs. 5 and 7. Thejournal of the pulley H8 is continued, rearwardly through thesupporting-plate H26 and carries fast on its end the pinion H9,'whichgears into a pinion H111, also journaled inthe said plate H26. Thispinion H10 gears in turn into a third pinion H11, loose on the shaft,which carries the assembling-star H13, but which ordinarily causes therotation of the said shaft and star by reason of the spring connectionH12, fast on said shaft. This spring connection H12, however, permitsthe stoppage of the assembling-star H11'1 in case a matrix or space-bandshould bef come jammed or wedged in front of it, and thereby preventsthe breakage of the parts. In front of the assembling-star H13 and ofthe pulleys H7 and H8 a glass plate H15 is provided, which is held in aframe H17, (see Figs. 2 and 5,) pivoted at H18 in such manner vthat 'theplate H15 may be swung to the right, so

as.to permit access to the parts within. rlhe spring H16 holds the platefirmly when it is closed, and a set-screw H11 limits its inward motion.

The space bands or bars are suspended in their magazine K, are deliveredone at a time therefrom, and descend through the channel or conductor Kto the front of the assemblingblock, into which they are carried in thesame manner as the matrices and added to the line .in the course ofcomposition or assemblage.

`436`,532,previously referred to. It is provided, however, with apivoted cover K10, which is formed with a centrally-depending IOO lug orbar K25, which is so shaped as toproject between the lugs or ears Z2 ofthe spacebars. This cover when closed rests upon the stop K11 and holdsthe space-bars securely in the magazine, but does not prevent theliberation ofthe space-bars one by one by the escapement mechanismhereinafter to be described. (See more particularly Figs. 1, 26, 27, and28.)

The release of the space-bars one at a time is effected from thespace-bar key K2, (see Fig. 5,) pivoted at K3 and acting upon theescapement-rod K1, which acts in turn upon the end of the pivoted leverK5, (see Fig. 2,) which is pivoted to the escapement-lever proper, K6,pivoted at the base of the magazine K. At the end of theescapement-lever K6 are pivoted the escapement-pawls K7, which arenormally held inward against the magazine by the springs Ks in suchmanner that the pawls K7 will engage one, and only one, of the spacebarsin the magazine. Fast to the lower end of the magazine K is theprojecting piece K2, which rests in contact with the outer or eX- tremespace-bar and holds the series from further downward movement until theouter one is released by the action of the escapement-pawls. )Vhcn thefinger-key K2 is depressed through the connections already described,the pawls K7 are elevated and engage under the shoulders Z2 of theoutermost spacebar Z and lift it until it is free from the piece K9 anduntil its upper shoulders are raised above the side of the magazine,when the weight of the assembled series of space-bars forces it over thebeveled portion K13 of the magazine K into the channel K', permitting itto drop into position in front of the assembling-star H13, whereby it isforced into the assembling box I. The delivery of more than onespace-bar at one operation is provided against by means of the studs K12on the pivoted cover K10, (clearly shown in Figs. 27 and 28,) which aresquared off and formed in such fashion as to permit the escape of asingle space-bar at a time. As before noted, the spring guide-piece H14serves to check the too rapid fall of the space-band by reason of itsprojecting tongue.

In order to resist the advance of the lengthening line of matrices andto hold them in compact order, I provide the yielding resistant J, whichis forked and straddles the guidepiece J', as clearly shown in Figs. 2and 6. This resistant J is provided with a finger, which projects downand into the assemblingbox, against which the line of matrices andspace-bands is assembled. As clearly shown in Figs. l and 2, it isconnected to the cord or band J2, which passes about the compound pulleyJ3, around which also passes the cord J1 to the spring J5, attached tothe frame of the machine. As will be clearly seen, the tendency of thisarrangement is to draw the resistant J to the right and to oppose theenlarging line of matrices and space-bands,

which is constantly urged forward by the action of theassembler-star'lfl.

The length of the line is determined by the pawl or detent L, whichdepends from the slotted rock-shaft L2 and'which is adjustably attachedthereto by the set-screw L3 in such manner that the length of the linemay be dctermined at will. A spring L4, attached to the frame of themachine and to the rockshaft L2, tends to force the pawl L forward intothe path of the resistant J, but permits the pawl to be swung rearwardlyand out of contact with the resist-ant when the line is full, as shownin dotted position in Fig. 6, so that the line of matrices andspace-bars may be shifted to the elevator at the left.

The construction of the assembling-box I is clearly shown in Fig. 6 andconsists of a box open at the top and at the two ends, so that the lineof matrices and space-bands may pass in and out. It is further providedwith shoulders to engage the lower shoulders Y of the matrices, therebysustaining them. The space-bands are sustained in the assembling-box byreason of their shoulders Z2, which pass over the upper edges of thebox. The front of the assembling-box I is provided with a longitudinalslot I/ to enable the operator to see the indicating characters whichdistinguish the matrices. Vhen a complete line of matrices and space-bands has been assembled, the pawl L is moved rearwardly by theoperator against the pressure of the spring L4, and the line of matricesand spacebands, together with the resistant, is moved manually to theleft along the guideway M until it is inserted and received within theelevator N, which when the machine is at rest is normally in line withthe guide M and assembling-box I. In effect the guideway M is a merecontinuation of the assembling-box. It will be seen that by thisarrangement and the simple manual transfer of the composed line I amenabled to dispense with the first line-elevator, the transferringmechanism, and their operating-levers and cams, as illustrated in myLetters Patent Nos. 436,531 and 436,582, previously referred to.

When the elevator descends in the manner hereinafter to be described,the resistant J is left free to return to its original position in theassembling-box by reason of the spring connections J2, J3, J1, and J5,previously described. In this return'movement of theresistant J itencounters the bevel L5 on the pawl L and effects the rearward movementof the said pawl against the pressure of the spring L4, permitting thepassage of the resistant J to its original position in theassembling-box. Then the operator may proceed to the composition ofa'second line, as the operations of justification, locking, casting,slug trimming and delivering, and of the distribution of the matricesand space-bands of the rst line are automatically accomplished in theoperation of the machine.
